CAS number : 18820-29-6
Molecular weight :
Molecular formula/chemical symbol :MnS
Description :
Manganese(II) sulfide can be prepared by reacting a manganese(II) salt (such as manganese(II) chloride) with ammonium sulfide:
(NH4)2S + MnCl2 → 2 NH4Cl + MnS
The crystal structure of manganese(II) sulfide is similar to that of sodium chloride.
The pink color of MnS likely results from poor coupling between the lowest energy unoccupied Mn orbitals, resulting in discrete states rather than a delocalized band. Thus the lowest energy band-to-band electronic transition requires very high energy (ultraviolet) photons.
